The Code That Forgot to Read the Room
De Filippi and Wright wrote this book at the precise moment when blockchain's theoretical elegance still outpaced its practical humiliations. Published in 2018, *Blockchain and the Law* is a careful, measured attempt to map the collision between decentralized systems and centralized legal authority — a collision the authors correctly identified as inevitable but whose specific wreckage they could not have predicted. They got the physics right. They got some of the geography wrong. The book treats blockchain as a serious infrastructural shift rather than a speculative gold rush, which was the intellectually honest position in 2018 and remains, in a battered way, defensible now. What it could not account for is how thoroughly the speculative gold rush would consume the oxygen, leaving the serious infrastructural work gasping in a corner while billion-dollar meme coins and celebrity-endorsed token launches dominated the public narrative through 2024 and into 2025.
The book's most prescient contribution is its sustained attention to the regulatory vacuum — the gap between what decentralized systems can do and what existing law can reach. The authors foresaw that pseudonymous transactions and autonomous smart contracts would generate enforcement nightmares, and they were right. The SEC's years-long campaign against crypto exchanges, the EU's Markets in Crypto-Assets Regulation, the Treasury Department's expanding sanctions enforcement against mixer protocols — all of these were embryonic in the dynamics De Filippi and Wright described. Their framing of blockchain's "dual-use" nature, enabling both legitimate innovation and illicit activity, anticipated the exact rhetorical battleground that regulators and advocates have been fighting over since. They also grasped, earlier than most legal scholars, that smart contracts would create novel liability questions — who is responsible when autonomous code executes a transaction no human specifically authorized? The collapse of several DeFi protocols and the legal chaos surrounding DAO exploits have made this less a thought experiment and more a litigation docket.
Where the book now reads as a product of its moment is in its implicit faith that the technology's decentralizing potential would be its defining feature. The years since publication have demonstrated, with some brutality, that decentralization is expensive, slow, and politically inconvenient — and that most users don't actually want it. The consolidation of crypto activity around a handful of centralized exchanges, the dominance of a few mining pools and validator networks, the rise of centralized stablecoin issuers like Tether and Circle as the actual load-bearing infrastructure of the ecosystem — none of this fits the cypherpunk vision the book traces with such care. De Filippi and Wright acknowledged the cypherpunk roots without fully interrogating whether the ideology was load-bearing or decorative. By 2026, the answer is mostly decorative. The book also has little to say about environmental costs, which became a major political and regulatory lever, or about the specific social dynamics of crypto communities — the cult-like governance structures, the influencer-driven pump cycles, the way "trustlessness" in practice often meant trusting anonymous developers with fewer accountability mechanisms than a small-town bank.
The book's position in the intellectual landscape is that of a bridge. It took the libertarian technologist arguments of the 1990s cypherpunks and the early Bitcoin evangelists and translated them into the language of legal scholarship, making them legible to regulators and policymakers. This was genuine service. It gave successors — legal scholars, policy analysts, even judges writing opinions on crypto cases — a framework for thinking about code-as-governance that didn't require buying the whole ideological package. Lawrence Lessig's "code is law" formulation from two decades earlier is the obvious ancestor; De Filippi and Wright updated it for a world where the code wasn't just regulating behavior on platforms but attempting to replace financial intermediaries entirely. The book's sober tone now reads as almost quaint against the carnival that followed, but sobriety ages better than hype.
Eight years on, with governments worldwide having chosen varying degrees of accommodation and crackdown, with blockchain technology quietly embedded in some supply chain and settlement systems while loudly failing to revolutionize most of what it promised to revolutionize, the book raises a question it could not have raised in 2018: If the law has largely succeeded in reasserting jurisdiction over decentralized systems — through exchange regulation, stablecoin oversight, sanctions enforcement, and sheer prosecutorial will — does that mean the "rule of code" was never really a rival to the rule of law, but only ever a stress test of it?
